Solution Overview

Linkwen Electronics provides a new-generation, highly integrated ONU testing platform designed for production lines and R&D testing environments.

The system integrates functions such as BOB calibration, traffic generation testing, optical path switching, TX optical power measurement, and Wi-Fi coupling strength testing. It supports mainstream standards, including GEPON, GPON, XGPON, XGSPON, 25G PON, 50G PON, and FTT The modular architecture allows users to flexibly expand test boards and quickly configure the system according to production scale or application needs, significantly improving testing efficiency and accuracy.
